NUMERICAL MODELING OF THE THREE-DIMENSIONAL UNSTEADY CONVECTION OF A SILICON MELT IN A VESSEL TYPICAL OF CZOCHRALSKI-METHOD APPARATUSES
N. G. Ivanov and E. M. Smirnov UDC 532.516:536.25 Calculations of the quasiperiodic and stochastic regimes of three-dimensional convection of a silicon melt (Pr = 0.015) have been performed for a rotating vessel whose complicated shape is typical of crucibles used in growing crystals by the Czochralski method. A large set of data on the structure of the convection and the spectral composition of pulsations has been obtained. The influence of the rotation of a crystal and a crucible on the convection and the thermal state of a melt has been investigated.
